| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Advanced Chemistry (advanced_chemistry) | enabling | 82% | review | Modern synthetic pesticide systems depend on industrial organic chemistry; DDT's insecticidal use was discovered in 1939 and scaled during World War II. |
|
| Mechanized Tractors (mechanized_tractors) | commercial_or_scaling_dependency | 55% | expert_inference | Mechanized tractors and sprayers scale field application, but synthetic pesticide chemistry does not strictly depend on tractor technology. |
